Gatling Enterprise MQTT error


We are using Gatling Enterprise and created a simple scenario that basically does a connection for a device and nothing else. In Gatling we do see that the number of users keep ramping up, but in our load balancer of the MQTT broker that we host we see the following message:

MQTT protocol error on connection → connect_expected

We are not quite sure why we see this response, do you might have an idea why we might be seeing this?
